A ROM update from Hong Kong for the HTC Touch Diamond released yesterday adds some fantastic functionality such as the use of the 850MHz GSM band (used by AT&T here in the US) and the improved TouchFLO 3D performance. (For the record, the performance update is great.) There are also a few bug fixes like the "no signal issue" and home page loading. Grab it at the links from XDA Devs. [XDA Devs]
